Before version 3.x, the {$cliName} required a project to have a "repository"
directory containing the Git repository, "builds", "shared" and others. From
version 3, the Git repository itself is treated as the project. Metadata is
stored inside the repository (in {$localDir}) and ignored by Git.

This command will migrate from the old file structure to the new one.
